Error creating calendar and iFrame type content

[GoodVice]

Hello everyone,

The first thing I would like to know is if this project is still alive, I say this because the website seems to have not been updated since 2022. 

I am a teacher and I want to install Concerto in our school. Everything seems to work correctly except when I try to add a calendar or an iFrame. When I try to add a Google calendar using iCal and the secret calendar address, I get the following message "1 error prevented this calendar from being saved:

Could not fetch calendar - execution expired". There is some documentation that explains how to do it because I can't find anything online. On the other hand, when I add an iFrame, I can see it in the content preview but then it doesn't appear on the screen it is subscribed to. Are iFrames displayed in graphic type fields? because I see that it is the type of item that appears approved.

I would greatly appreciate any help.

Best regards

Víctor.
